It goes on to say that, in "cool" mode, when auto fan is selected the fan speed will vary depending on the difference between the temperature set-point and the room air temperature. In auto fan the compressor and the fan will cycle On and Off with the thermostat.

Thanks for posting the manual. The dealer did not have the manual for the thermostat in the packet of manuals they gave me. Thanks again everyone for the help.

Hello everyone! I just got my first camper in July. A Crusader 325RES. So far we love it. I'm having an issure with the a/c tho. No matter what temp setting I set the unit runs all the time. I turned it to 90° tonight and it kept running. I have a digital thermometer that says my camper is 70.4° so I'm not sure why it wont kick off. Any ideas?

It doesn't look like anyone is understanding your problem correctly. If you have temp set at 90 deg and it is going to 70.4 degrees, it is not a thermostat setting problem. I am assuming you can shut down the whole unit if you want. Unless I am the one that is confused, it sounds like you may have a wiring problem. Sounds like a 2 wires are touching each other and thermostat can't turn off compressor. I would guess wires behind thermostat could be touching each other, maybe too much insulation taken off.

Exactly! When I turned the temp to 90° and left it like that for 5min it was still running. Ill take it apart tomorrow and see if I can find a problem.

Had the same problem with our Ultralite 2304s. AC would not shut off, just got colder and colder. Dealer repair notes said "relocate AC/heat thermostat on/off switch, rewire, repair holes in previous location". Not sure why they moved it, but you would never be able to tell if you did not know. It originallywas quite high up, maybe a foot below the ceiling and now is about the level of the fridge handle. Warranty job just after we took delivery.

Timarti could be right too. It could be a miswire too. If you don't see anything obvious, it may be time for your dealer to correct it. Also thanks to TRIGUY for instruction manual. I learned how to see the actual temp in camper and learned there are filters in system. Cleaned them last night.
